Structure of upper and insole of shoes

ABSTRACT

A shoe with both functions of waterproof and ventilation includes an upper fabric including a ventilation film, on which a plurality of apertures are provided, a bottom fabric sewed on the upper fabric directly and an insole attached on the bottom side of the bottom fabric. The bottom fabric has two protrusion pieces on opposite edges, and the upper fabric has two portions associated with the protrusion pieces bent inwards to be attached on a margin of a bottom side of the bottom fabric and sewed thereon, such that the protrusion pieces are left at an inner side of the upper fabric.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a shoe, and more particularlyto a structure of upper and insole of the shoe.

2. Description of the Related Art

Conventional shoes have waterproof function, especially for somespecific functional shoes, such as jogging shoes. People usually jog inthe morning, and jogger may steps on the grass with dew thereon and wetthe jogging shoes. To keep jogger's feet dry, the shoes usually isprovided with a waterproof film. The waterproof film makes the shoeshaving waterproof capacity, and it introduces a new problem.

The waterproof films bar water out of the shoes and keep moisture in theshoes. In other words, such shoes don't ventilate. Joggers wearing suchshoes will feel wet, stuffy and hot, especially when jogger sweats andincreases body heat in running. In such condition, jogger needs shoeswith greater power of ventilation to reduce the uncomfortable feeling.

In addition, the conventional shoe usually has the upper sewed into theinsole directly. Such shoes will make people stepping on two differentparts and the sewing portion that make people uncomfortable, especiallyon the heel. It also may break the thread of sewing when a person wearsthe shoes for a long time.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a shoe withboth functions of waterproof and ventilation.

According to the objectives of the present invention, a shoe with bothfunctions of waterproof and ventilation includes an upper fabricincluding a ventilation film, on which a plurality of apertures areprovided, a bottom fabric sewed on the upper fabric directly and aninsole attached on the bottom side of the bottom fabric. The bottomfabric has two protrusion pieces on opposite edges, and the upper fabrichas two portions associated with the protrusion pieces bent inwards tobe attached on a margin of a bottom side of the bottom fabric and sewedthereon, such that the protrusion pieces are left at an inner side ofthe upper fabric.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1 to 4, a shoe of the preferred embodiment of thepresent invention includes:

An upper fabric 10 includes a ventilation film 11, on which a pluralityof apertures 12 are provided for ventilation, and two fabrics 13sandwiching the ventilation film 11. The upper fabric 10 has bothfunction of waterproof and ventilation because of the apertures 12 ofthe ventilation film 11. The fabrics 13 may be made of cotton, nylon orpolymer.

A bottom fabric 20, which is an elongated member, has two protrusionpieces 21 on opposite edges. The protrusion pieces 21 may be located ata middle of the bottom fabric 20, as shown in FIG. 2, or a rear thereof,as shown in FIG. 4. The widths and lengths of the protrusion pieces 21are adjustable to meet the requirement. The upper fabric 10 has itsbottom edge sewed on a margin of the bottom fabric 20 directly. Theupper fabric 10 has portions associated with the protrusion pieces 21bent inwards to be attached on a margin of a bottom side of the bottomfabric 20 and sewed thereon, such that the protrusion pieces 21 are leftat an inner side of the upper fabric 10, as shown in FIG. 3. The bottomfabric 20 may be made of cotton, nylon or polymer.

An insole 30 is attached on the bottom side of the bottom fabric 20 byan adhesive. The adhesive has ventilation property but waterproofproperty.

The shoe of the present invention has both functions of waterproof andventilation because of the ventilation film 11. The ventilation film 11provides the waterproof function and the apertures 12 on the ventilationfilm 11 provide the ventilation function that overcomes the problemdescribed in the background of the invention.

In addition, the upper fabric 10 has the portions associated with theprotrusion pieces 21 bent inwards to be attached on a margin of a bottomside of the bottom fabric 20 and sewed thereon, such that the protrusionpieces 21 are left at an inner side of the upper fabric 10 rather thansewing together directly. This kind of structure may let a person whowears the shoes of the present invention has feet stepping on the bottomfabric 20 to prevent thread sewing the upper fabric 10 and the bottomfabric 20 from break and to elongate the product life.

The description above is a preferred embodiment of the present inventionand the equivalence of the present invention is still in the scope ofthe claim of the present invention.

1. A shoe, comprising: an upper fabric including a ventilation film, onwhich a plurality of apertures are provided, so that the upper fabrichas both functions of waterproof and ventilation; a bottom fabric, whichis an elongated member, having two protrusion pieces on opposite edges,wherein the upper fabric has a bottom edge sewed on a margin of thebottom fabric directly, and the upper-fabric has two portions associatedwith the protrusion pieces bent inwards to be attached on a margin of abottom side of the bottom fabric and sewed thereon, such that theprotrusion pieces are left at an inner side of the upper fabric; and aninsole attached on the bottom side of the bottom fabric.
 2. The shoe asdefined in claim 1, wherein the upper fabric further includes twofabrics sandwiching the ventilation film.
 3. The shoe as defined inclaim 2, wherein the fabrics are made of cotton, nylon or polymer.
